Abstract: Some embodiments facilitate creation of an industrial asset item via an additive manufacturing process. A laser source may receive a laser power command signal PC and generate a laser beam output in accordance with PC. A first sensor may measure a power PD of a laser beam delivered for the additive manufacturing process. A second sensor may measure a power PO associated with the laser beam output from the laser source, wherein at least a portion of an optic train is located between the first and second sensors. A monitoring apparatus, coupled to the first and second sensors, may monitor PC, PO, and PD to facilitate creation of the industrial asset item. Responsive to the monitoring, the system may control at least one aspect of the additive manufacturing process, automatically generate an advisory indication, automatically localize a detected problem in the system, automatically predict a future performance of the system, etc.
